The move, reported by CNN Monday, signals they will both be deeply involved in the forthcoming Trump administration after he takes office on January 20.

On Monday, Ivanka held a meeting with Leonardo DiCaprio, a prominent environmentalist. The Oscar winner even gave Trump’s oldest daughter a copy of his climate change documentary, Before the Flood, which was released last month.

Another prominent fighter against climate change, former Vice President Al Gore, met with both Donald Trump and his daughter at Trump Tower Monday afternoon.

Gore, also an Oscar winner thanks to his climate change documentary An Inconvenient Truth, told reporters outside the building: "I had a lengthy and very productive session with the president-elect. It was a sincere search for areas of common ground. I had a meeting beforehand with Ivanka Trump."

He added: "The bulk of the time was with the president-elect, Donald Trump. I found it an extremely interesting conversation, and to be continued, and I’m just going to leave it at that."
